Migration Theories Inquiry - Assignment Overview
In this inquiry assignment, you will read a short article and watch several short videos. When instructed, you will answer guide questions to help you understand how, when, and why archaeologists and other scientists believe the first people migrated to North and South America. You may need to pause the videos as you watch so that you can answer the guide questions thoroughly.
When your guide questions have been answered, you will complete a graphic organizer to help organize your ideas. Then, you will complete a project where you explain the various theories discussed in the article and videos about human migration to North and South America.
First, watch this introductory video on the First Americans.
Third, read the Migration Theories article and answer the accompanying guide questions.
During the last Ice Age, about 21,000 years ago, global sea level was approximately 120 m (400 ft) lower than today. The Bering Land Bridge existed as a vast tundra plain connecting Asia and North America. As the world's glaciers and ice sheets melted over thousands of years, rising sea level flooded the land bridge — blocking migration routes for animals and humans.The land bridge animation below is based on the best available digital information, and reveals large-scale patterns of shifting coastlines and environments as the land bridge evolved.
